Face Fault
A face fault is when a character gets so shocked they crash like a clumsy elephant. It's the anime version of getting hit by a truck.
I Face Faulted during Attack on Titan when Eren turned into a titan. I nearly broke my chair.
My brother Face Faulted during Demon Slayer and fell off the couch. He’s still sore.
During Fairy Tail, my cat Face Faulted and knocked over my cereal bowl.
